However, this is no ordinary ping-pong ball, it is ultra-clean, smaller than regulation size and fitted with a radio transmitter. This so called radio-frequency ball was used to test that the connections between the magnets are free from any defects.
Researchers at the Super Cryogenic Dark Matter Search (CDMS) facility have recently uploaded a paper in which they announce that they have found three events that lie in the signal range of a Weakly Interacting Massive Particle (WIMPs). Continue Reading
